  • The present study is purposed to establish a systematic theory for user-friendly approach to the creation of using a programming language using Csound. Csound is a world-wide computer music programming language and a software synthesizer specialized for prominent sound designers developed by Barry Vercoe at the Media Laboratory in M.I.T. The introduction and the main body of this paper suggested as the starting point of creating electronic music and musical sound the time of combination of music with natural sound or sound from specific media from the viewpoint of traditional Western music. and presents a systematic method composed of the principle of the operation of Csound and basic data samples.

  • Due to advances in machine intelligence and increased demands for autonomous machines, the complexity of the underlying software platform is increasing at a rapid pace, overwhelming the developers with implementation details. We attempt to ease the burden that falls onto the developers by creating a graphical programming framework we named Splash. Splash is designed to provide an effective programming abstraction for autonomous machines that require stream processing. It also enables programmers to specify genuine, end-to-end timing constraints, which the Splash framework automatically monitors for violation. By utilizing the timing constraints, Splash provides three key language semantics: timing semantics, in-order delivery semantics, and rate-controlled data-driven stream processing semantics. These three semantics together collectively serve as a conceptual tool that can hide low-level details from programmers, allowing developers to focus on the main logic of their applications. In this paper, we introduce the three-language semantics in detail and explain their function in association with Splash's language constructs. Furthermore, we present the internal workings of the Splash programming framework and validate its effectiveness via a lane keeping assist system.

  • In this paper, we investigate the feasibility of functional programming in the Scala language. The main issue is to what extent Scala is able to handle major properties of functional programming such as lambda expression, high-order functions, generic types, algebraic data types, and monads. For this purpose, we implement an interpreter of an imperative language. In this implementation, the same functional programming techniques are applied to both Haskell and Scala languages, and then these two versions of implementations are compared and analyzed. The abstract syntax tree of an imperative language is expressed as algebraic data types with generics and enum classes in Scala, and the state transition of imperative languages is implemented by using state monad. Extension and given, new features of Scala, are used as well.

  • Refactoring is an engineering technique for securing the quality of existing legacy code, improving the internal structure without changing the functionality of the software. Along with the reuse of open source software, reuse of source code through programming language conversion is increasingly required due to technical or market requirements. In this situation, the refactoring technique including language conversion as well as energy efficiency is considered to be an important means for improving the productivity and the quality of embedded software development. This paper proposes a code refactoring technique that converts the grammar and structure of a programming language into those of a different language through comparison and mapping, in addition to the existing energy efficient refactoring technique. The use of the proposed refactoring technique can expect to improve the competitiveness of the product through rapid software development and quality improvement by coping with the environment change of the software development language and enhancing the reuse of the existing code.

  • The R language is an open source programming language and a software environment for statistical computing and data visualization. The R language is widely used among a lot of statisticians and data scientists to develop statistical software and data analysis. The R language provides a variety of statistical and graphical techniques, including basic descriptive statistics, linear or nonlinear modeling, conventional or advanced statistical tests, time series analysis, clustering, simulation, and others. In this paper, we first introduce the R language and investigate its features as a data analytics tool. As results, we may explore the application possibility of the R language in the field of data analytics.

  • To learn a programming language as a text-based programming and a computer language suitable for a wide range, learner thinks it is very difficult. To represent a visual program is one way to solve this problem easily. The visual language such as Visual C++, Visual Basic and Delphi is represented an interface as the visual component and represented a component action as a text-based. The programmer is very difficult about the component action with text-based and dislikes programming. In this paper, so solve these problems, we use the UML for representing a logical thinking and supporting and object-oriented programming. We suggest for programming education method to replace text-based programming to LabVIEW OOP. In addition, we conduct a survey on how programming education and analyze the training effect.

  • Lately, studies on the educational effectiveness of educational programming language which can reduce the learning burden of the learners have been conducted in the programming learning process. This study analyzed the effect of programming education on the learning motivation and academic achievement after training the programming education using Scratch and Dolittle on the preliminary elementary school teachers. As a result, the experimental group trained by Scratch programming education showed significantly higher achievement than the control group by Dolittle Programming. This result can be helpful in selecting educational programming language when the programming education will be trained to the preliminary elementary school teachers.

  • Robot programming has been discussed in detail during the recent years. Numerous studies in particular presented relevance, solution concepts and implementation of off-line programming. In this paper a new user-friendly robot programming method is introduced, which permits the implicit description and programming of assembly process. On the functional level of programming, the assembly processes are described in terms of their operational functions. On the language level, the individual functions are then translated into commands for the robots.

  • In computer education area, abstract thinking has played a positive role in programming ability, and language experience has also affected the ability. However, most of the studies were empirical. The practical research about the relation analysis between abstract thinking and programming ability has rarely been performed. Among various types of programming abilities such as coding, debugging, and reading, this paper focused on program understanding. We analyzed the affection relation on program understanding and the interaction effect between abstract thinking level and language familiarity. We surveyed 376 high school students on their abstract thinking levels, language familiarity, academic achievement, and the program understanding abilities of C and Scratch. From the research, we knew that the abstract thinking level played an important role in understanding the iterative program for the male students. In addition, if the students had the experience on other programming languages before entering high schools, then there was an interaction effect between abstract thinking level and program language familiarity.

  • The software Process can be defined as the set of activities, rules, procedures, techniques and tools used within the production of software. A software process model is a conceptual representation of a real world software Process and can be described by process programming languages. In this paper, we present the language constructs of SimFlex designed for object-based software process programming. The design of SimFlex is based on the object concept, so that it can model complex software processes concisely both in syntax and semantics. Since the language constructs of SimFlex are derived from the analysis of major PSEEs and their associated process programming languages, SimFlex includes the core characteristics required for a desirable object-based process programming language. In addition, SimFlex is designed to act as a template software process definition language which could be included in specific PSEEs through customization appropriate to those PSEEs.
